Answer:

they are rational numbers

Step-by-step explanation:

Any fraction with integers in numerator and denominator is a rational number.

5, 6, 7, 11 are integers, so the fractions 5/11 and 7/6 are rational numbers.

PLease help me out with this...I will mark the first one as the brainiest answer.

You cannot add row 2 to column 3 because they have different dimensions. You can do any of the other operations, but the only one that makes any sort of sense is ...
Multiply row 2 by -1 and add it to row 3

_____
It makes no sense to multiply a row by zero. That makes the entire row zero and makes the matrix useless for finding any sort of solution.

You can switch columns, but that doesn't get you any closer to a solution here.

If I were trying to find a solution, I might
switch rows 1 and 2
multiply the new row 1 by -3 and add it to the new row 2
multiply the new row 1 by 2 and add it to row 3
This sequence of operations will make the first column [1 0 0], reducing the problem to 2×2 from 3×3.

Answer: A. $\left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]$

Step-by-step explanation:

The question is asking us to find the product of the matrices. The key difference is the second A has a little <em>T</em> in the exponent. This <em>T</em> means transpose. You multiply A by the transpose of A. To find the transpose, you turn the rows into columns.

$A^T=\left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right]$

Now that we have our transpose, we can multiply the matrices.

$\left[\begin{array}{ccc}5&2\\3&-1\\\end{array}\right] \left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right] =\left[\begin{array}{ccc}5*5+2*2&5*3+2(-1)\\3*5+2(-1)&3*3+(-1)(-1)\\\end{array}\right] =\left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]$

Answer:

The correct answer is Option 3: 12y

Step-by-step explanation:

A polynomial term is usually made of a variable and a co-efficient.

Like terms are those terms that have the same variables i.e. x and 44x are like terms.

Given expression is:

$6y-2y+8y$

All the terms have only y which means that all three terms are alike.

The coefficients of like terms are added or subtracted according to their sign.

$6y-2y+8y$ = 12y

Hence,

The correct answer is Option 3: 12y
